Answer:
Therefore the required Equation of Circle
Step-by-step explanation:
Given:
End point of Diameter be
point A( x₁ , y₁) ≡ ( -2 ,-2 )
point B( x₂ , y₂) ≡ ( 4 , -10 )
To Find:
Equation of a circle =?
Solution:
When end points of the Diameter are A( x₁ , y₁) , B( x₂ , y₂). then the Equation of Circle is given as
Substituting the end point are
Applying Distributive Property we get
Therefore the required Equation of Circle
Answer:
Range =94
σ² = 1,141.564
Standard Deviation = 33.78703
Step-by-step explanation:
First off to find the range, we find the highest value and subtract it to the lowest value. In this situation the values are:
Highest = 99
Lowest = 5
Range = 99 - 5
Range = 94
Now to find the variance of the sample data set, we first need to find for the mean of the data.
The mean of the data with be the sum of all the numbers in the data set divided by the number of samples.
5 + 14 + 26 + 50 + 60 +72 + 79 + 88 + 93 +94 + 99
That would equal 680
Then you divide the number of samples and that is 11 so the next equation is 680 divided by 11
So the then-
Mean = 61.81818
Now to find the variance we simply use the formula:
Now to find the variance we simply use the formula:
σ²=
σ²=
σ²=
σ²=
Now to find the standard deviation, we take the variance and get the square root of it.
Standard Deviation=
Standard Deviation=
